The launch of the second-generation XC90 marked the beginning of a new era for Volvo a couple of years ago. The XC90 is the first model to ride on the company’s all-new scalable product architecture (SPA), the first all-new platform to come from Gothenburg since Ford sold the Swedish brand to China’s Geely in 2010. After initially being available only with boosted four-cylinder engines, the XC90 is now the first regular production plug-in model Volvo is offering in America and I recently spent a week driving one.
